Hello, To compile a custom kernel, I downloaded 2.6.29.1 from kernel.org and followed the tutorial at: http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen Used a supposedly working .config file for the compilation (generated by my provider to compile his xenU kernels), set /dev/xvd* device nodes both in the domU conf file (disk, root): disk = [

We have DELL server with MD1000 Disk array in it. O.S. is CENTOS 5.5. Recently every time MD1000 "patrol read" start I will get "media error" messages on /var/log/message file. I use MD1000 "slow initialize" to initialize "bad disk" and NO error. After "slow initialize" finish, I manually "startup patrol read". I continue get

I''m trying to get a new file server managed by puppet from day 1, at least as much as possible. At the moment, though, there''s two issues I''m running into: 1. fstab should have entries for my comically-large RAID, but doesn''t. 2. each puppet run appears to remount the RAID, even when no rules in the manifest change. I suspect the issue may be in parsing

I have some Xen systems running Xen-4.1.1, dom0 linux-2.6.38 patched (it''s gentoo''s xen-sources) and domUs running linux-3.0.4 (vanilla sources from kernel.org). Block devices are phy on LVM2 volumes on DRBD-8.3.9 devices. Not immediately after boot, but after some I/O load on the disks I start seeing these in the domUs: blkfront: barrier: empty write xvdb1 op failed blkfront:

I have 15x SAS drives in a Dell MD1000 enclosure, attached to an LSI 9200-16e. This has been working well. The system is boothing off of internal drives, on a Dell SAS 6ir. I just tried to add a second storage enclosure, with 15 more SAS drives, and I got a lockup during Loading Kernel. I got the same results, whether I daisy chained the enclosures, or plugged them both directly into the LSI

Hello, I''ve installed XenExpress 3.2. Within a DomU (Debian) I want to recompile the kernel.

Hi list, I setup on 2 Xen Dom0s drbd/gfs a logical volume, this works as primary/primary so both DomUs will be able to write on them at the same time. But I dont know how to mount them from my domUs, I can see them with fdisk -l. The partition is /dev/xvdb1 SHould I install gfs on domUs and mount them on each as gfs partitions? [root@p3x0501 ~]# fdisk -l Disk /dev/xvda: 5368 MB, 5368709120

Hi, I have a Xen server running OpenSuSE 10.2, with Xen version 3.0.3_11774. It''s happily hosting two DomU''s running the same OS / kernel. Now I tried to create a new DomU running a newer OS - OpenSuSE 11.1. It comes with Xen version 3.3.1_18494_03. Unfortunately for me, it doesn''t work - this is what I get: > xen1:/etc/xen/vm # xm create NEW > Using config file

I need to replace a slow HP MSA20 that's a bottleneck right now (We are an HP shop). HP's only option with 3.5" SATA drives is stuck at SATA I behind a SAS controller. Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don't know anything about dell). Anyone got any real world info they can share? I need 3.5" SATA II at least 12 drives behind SAS, I am
